Abstract

The invention provides manufactured shaped articles, more particularly elastic films and fibers, having excellent characteristics. The articles are transformation products of certain terpolymers of ethylene, propylene, and hydrocarbon monomers containing at least two double bonds, which terpolymers contain, by mols, 70-85 percent ethylene, 15-30 percent propylene, and 0.05-3 percent of the polyene, have a molecular weight above 20,000, and are amorphous in the relaxed state but crystallize under stretching, more particularly after vulcanization.
